MR-13U has a rather big battery therefore it takes a long time to charge it. It might seem for the first time that nothing happens after connecting a charger. The router has 5 leds (4 blue and 1 red) to indicate the battery status. When you press the battery button status LEDs light up.

MR-13U has a rather big battery therefore it takes a long time to charge it. It might seem for the first time that nothing happens after connecting a charger. The router has 6 leds of which 4 blue and 1 red are used to indicate the battery status. When you press the battery button status LEDs light up.

When the battery charging is in progress LEDs stay on and after it's finished they go off. While charging the router consumes about 7W (measured with watt meter in power outlet)

If the battery level is low one red LED light up and stays this way even if the battery check button is released. ​
